The authors measure the low temperature heat capacity of a Pd‐based metallic glass and derive the Boson peak height in relation with the enthalpy changes occurring upon structural relaxation and crystallization. The Boson peak height was also calculated within the framework of the Interstitialcy theory as a function of the excess enthalpy of glass with respect to the maternal crystal. A good agreement between experiment and calculation is found.
